media: ov08x40: Reduce start streaming time

Because video duration involves calculating the streaming time, and i2c
communication incurs too many XTALK register settings every 4 bytes with
i2c START and STOP.

So we have opted switch to the i2c burst method.
This method involves writing the XTALK registers in the order of
the register block.

The start streaming time can be reduced from around 400ms to 150ms
